While surfing around for information about open source java platforms, I found a new way to web surf on the last line of this page of JOnAS documentation:

1. start tomcat, using for example the script shown previously. It may be useful to run tomcat with a CLASSPATH upgraded with the .jar files of the beans used by servlets and JSPs, because for some reason, tomcat sometimes fails to find this .jar file in its lib directory.
2. start the EJBServer
3. Use your brother to access the welcome page, usually index.html
